[SPARK-48353][SQL][FOLLOWUP] Enable ANSI for SQL Scripting execution suites

### What changes were proposed in this pull request?
Keep ANSI enabled for SQL Scripting execution suites to enable proper testing of exception handling.

### Why are the changes needed?
13 new tests in `SqlScriptingExecutionSuite` and `SqlScriptingE2eSuite` introduced in #49427 will fail to execute in non-ANSI mode and the NON-ANSI daily test failed:

If ANSI is off, code that should trigger exception fails silently (zero division does not throw). We want to keep ANSI behavior so that we can test exception handling properly.

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
Existing tests.

### Was this patch authored or co-authored using generative AI tooling?
No.
